Abstract
- A symbiotic and polymetallic ore containing copper and tin in Yunnan province is complex and the metallic copper and tin, and sulfur were mainly recovered. The oxidation rate of copper has increased and the recovery of copper has become difficult with continuous exploitation of the ore. Therefore, it was unsatisfactory that copper-sulfur flotation separation was carried out to obtain a qualified concentrate. The problems existing in the copper-sulfur flotation system were analyzed in detail according to the practical production. It was proposed to optimize the cyclone selection and operating parameters, to improve equipment configuration and reagent system in bulk roughers, to adjust reagent system in copper-sulfur separation roughers and the amount of grinding medium that were added into tower mill. The Cu grade and recovery in copper concentrate were improved by 3.34 and 3.76 percentage points, respectively. The copper-sulfur flotation system has reached the production standard and achieved good economic benefits for the mine. [ABSTRACT FROM AUTHOR]
